|dc.description.abstract||Background: In the early 20th century, René Le Fort studied facial fractures resulting from
blunt trauma and devised a classification system still in common use today. This classification,
however, was based on low-velocity trauma. In modern practice, in a quaternary-level referral
hospital, patients are often admitted following high-velocity injuries that mostly result from
motor vehicle collisions.
Objectives: A retrospective study to define facial bone fractures occurring subsequent to highvelocity
Method: A retrospective study comprising the review of CT scans of 52 patients with highvelocity
facial fractures was performed between April 2007 and March 2013. Injuries were
classified using the Le Fort classification system. Deviations from the true Le Fort types, which
are often depicted in the literature as occurring bilaterally and symmetrically, were documented;
these included unilaterality, occurrence of several Le Fort fractures on one side of the face,
occurrence of several Le Fort fractures on different levels and on different sides of the face, and
occurrence of other fractures in addition to Le Fort fractures.
Results: Of the 52 cases, 12 (23%) had Le Fort injuries, with true Le Fort fractures occurring in
only 1, and 11 deviating from the classic description. Nine patients had Le Fort fractures and
additional fractures. Mandibular and zygomatic bone fractures were found to be common
associations with Le Fort injuries, occurring in 58% and 33% of the cases respectively.
Conclusion: Fractures occurring in modern practice often deviate from the traditional Le Fort
classification. Precise recognition of these deviations and recognition of additional associated
fractures is pivotal in their management, assisting the surgeon in determining the treatment plan,
such as the surgical approach and the order in which to fix the various fractured components.||en_US
